RY610048 Equivalent & Substitute Parts

Part Overview

The RY610048 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays, configured as a Single Pole Double Throw (SPDT) contact form with an 8A contact rating and 48VDC coil voltage. This component is designed for through-hole mounting applications and features fully sealed construction with silver cadmium oxide contact material.

The RY610048 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure procurement availability, and support ongoing system maintenance and production requirements.

Substitute Part Grouping Explanation

Substitution of the RY610048 is determined by strict equivalence across the following critical parameters:

• Coil Voltage: 48VDC (exact match required)
• Contact Form: SPDT (1 Form C) (exact match required)
• Contact Rating: 8 A (exact match required)
• Switching Voltage: 400VAC maximum (exact match required)
• Mounting Type: Through Hole (exact match required)
• Coil Current: 5.1 mA (exact match required)
• Coil Resistance: 9.4 kOhms (exact match required)
• Operating Temperature Range: -40°C ~ 70°C (exact match required)
• Termination Style: PC Pin (exact match required)
• Seal Rating: Sealed - Fully (exact match required)

The RY611048 meets all substitution criteria. Variations in contact material composition and product status do not affect functional equivalence within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The RY611048 is the direct substitute for the obsolete RY610048. Both components are manufactured by TE Connectivity Potter & Brumfield Relays and share identical electrical and mechanical specifications across all critical parameters.

The RY611048 offers the following advantages:

• Active Product Status: The RY611048 maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: The RY611048 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
• Inventory Availability: The RY611048 is available in higher inventory quantities (1405 pcs) compared to the obsolete RY610048 (929 pcs).

The contact material differs between the two parts (silver cadmium oxide versus silver nickel); however, both materials are suitable for the specified electrical parameters and operating conditions. Selection between these parts should be based on product availability and regulatory compliance requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can the RY611048 be used as a direct replacement for the RY610048?

A: Yes. The RY611048 is a direct substitute for the RY610048. Both components share identical coil voltage (48VDC), contact form (SPDT), current rating (8A), switching voltage (400VAC), operating temperature range (-40°C ~ 70°C), and all other critical electrical and mechanical parameters.

Q: What is the difference between the RY610048 and RY611048?

A: The primary differences are product status and contact material composition. The RY610048 is obsolete with silver cadmium oxide contacts, while the RY611048 is active with silver nickel contacts. The RY611048 also carries ROHS3 compliance and REACH unaffected status. All functional electrical and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The RY610048 packaging is specified as a dash (-), while the RY611048 is supplied in bulk packaging. Both components use PC pin termination and through-hole mounting. Packaging format does not affect electrical or mechanical compatibility.

Q: Why should I select the RY611048 over the RY610048?

A: The RY610048 is obsolete, making long-term procurement difficult. The RY611048 is an active product with superior inventory availability, regulatory compliance certifications (ROHS3), and equivalent performance across all specified parameters.

Q: Do the different contact materials affect performance?

A: Both silver cadmium oxide and silver nickel contact materials are suitable for the specified 8A current rating and 400VAC switching voltage. Contact material selection does not impact functional equivalence within the defined electrical and mechanical parameters.

Q: What is the coil resistance of these relays?

A: Both the RY610048 and RY611048 have a coil resistance of 9.4 kOhms at 48VDC, with a coil current of 5.1 mA.

Q: What are the switching time specifications?

A: Both relays have an operate time of 9 milliseconds and a release time of 5 milliseconds.
